1. An apparatus comprising:
a processor;
a first port configured to connect to a second transmission apparatus through a first cable, wherein the first cable comprises a first number of main downlink lanes and a second number of main uplink lanes;
a first audio/video source adapter configured to:
obtain a downlink media signal, wherein the downlink media signal comprises at least one of a downlink video signal or a downlink audio signal;
encapsulate the downlink media signal to obtain a first downlink packet; and
send the first downlink packet;
a first multiplexer configured to:
receive the first downlink packet from the first audio/video source adapter;
pad the first downlink packet into a downlink data stream to obtain a padded downlink data stream; and
send the padded downlink data stream;
a first lane allocator configured to:
receive the downlink data stream from the first multiplexer;
allocate the downlink data stream to a first main downlink lane of the main downlink lanes; and
send the downlink data stream to the second transmission apparatus;
a first lane deallocator configured to:
receive an uplink sub-data stream from the second transmission apparatus through a first uplink lane of the main uplink lanes;
combine the uplink sub-data stream into an uplink data stream; and
send the uplink data stream;
a first demultiplexer configured to:
receive the uplink data stream from the first lane deallocator;
extract a first uplink packet from the uplink data stream; and
send the first uplink packet; and
a first audio/video sink adapter configured to:
receive the first uplink packet from the first demultiplexer; and
decapsulate the first uplink packet to obtain an uplink media signal.
